WordPress get-posts 没有内容（以减少开销）
场景：我正在侧边栏中创建可折叠面板，并将所有类别显示为 DIV，并在这些类别 DIV 中显示所有帖子链接。够简单的。我通过 get_categories('orderby=name&order=ASC') 获取了所有类别，现在循环遍历每个类别以获取每个类别中的所有帖子。
问题：代码get_posts('nopaging=1&category='.$category->cat_ID)为我提供了所有帖子，但带有内容还有其他的事情。我想要的只是该帖子的永久链接。就是这样。我相信使用 get_posts 会产生很大的开销，因为 20 多个类别中约有 1000 篇帖子。
解决方案：一个函数或一段代码，可以让我获得一个类别中带有永久链接的所有帖子，而无需其他内容，尤其是内容，因为它是最大的开销。
Scenario: I am creating collapsible panels in the sidebar and displaying ALL categories as DIVs and all Posts links in those category DIVs. Simple enough. I got all categories by get_categories('orderby=name&order=ASC') and now looping through every category to get ALL posts in each category.
Problem: The code get_posts('nopaging=1&category='.$category->cat_ID) gives me all posts but WITH content and other things too. All, I want is the permalink of the post. That's it. I believe using get_posts will thus create big overhead as there are around 1000 posts in over 20 categories.
Solution: A function or piece of code that can just get me all the posts in a category with permalink and without other stuff, especially content as it's the largest overhead.

考虑使用自定义查询来准确提取您想要的内容：http://codex.wordpress.org/Displaying_Posts_Using_a_Custom_Select_Query
完成自定义调用后，您可能还想使用 wp_reset_query()，因为当事情开始相互覆盖时，选择查询可能是 WordPress 中的一个有趣的陷阱：http://codex.wordpress.org/Function_Reference/wp_reset_query
在评论后编辑：您需要在 wp_term_relationships 和 wp_posts 之间使用联接，甚至可能与 wp_term_taxonomy 的 3 路连接起到了很好的作用。
说实话，我什至都不会费心——这需要大量的工作，但没有多少好处。 1000 条记录实际上并不算多，Wordpress 已经使用 wp_posts 上的索引来优化其查询。通过使用 wp super 缓存插件为访问者生成静态 HTML 文件，您可能会获得更好的结果（ http://wordpress.org/extend/plugins/wp-super-cache/ ），而不是通过复制核心 WP 查询并从选择中删除一些列。
Look into using a custom query to extract exactly what you want: http://codex.wordpress.org/Displaying_Posts_Using_a_Custom_Select_Query
You may want to also use wp_reset_query() after you've finished with your custom call because selecting a query can be a fun Gotcha in wordpress when things start overriding each other: http://codex.wordpress.org/Function_Reference/wp_reset_query
Edited after your comment: You'd need to be using a join between wp_term_relationships and wp_posts, possibly even a 3-way join with wp_term_taxonomy thrown in for good measure.
To be absolutely honest, I wouldn't even bother - it's a lot of work for not a lot of benefit. 1000 records isn't really that much, and Wordpress already uses indexes on wp_posts to optimise its' queries. You'd probably get much better results through using the wp super cache plugin to generate static HTML files for visitors ( http://wordpress.org/extend/plugins/wp-super-cache/ ) than by duplicating core WP queries with a handful of columns removed from the select.
